面向极端灾害的配-微电网两阶段协同优化运行策略
Two-stage Coordinated Optimal Operation Strategy for Distribution Network and Microgrid Under Extreme Disasters
摘要
Abstract
In recent years,the frequency and intensity of extreme weather events such as floods and typhoons have significantly increased,severely impacting rural distribution network(DN)with relatively weak grid structures,leading to large-scale and prolonged power outages..The resilience enhancement of rural power distribution networks is achieved through strategic deployment of microgrids(MG)in key user areas.This approach is necessitated by three rural characteristics:remote distance from centralized power sources,extended supply radii,and geographically dispersed load distribution.Distributed generation resources and mobile energy storage(MES)is systematically integrated to enable this infrastructure upgrade.To address this issue,this paper proposes a two-stage optimization model for the coordinated operation of distribution network and microgrid.In the pre-disaster phase,mobile energy storage is strategically deployed to ensure emergency power supply for critical local users.In the post-disaster stage,a restoration resource scheduling model is constructed,considering both MES and repair crews.Due to the different requirements of resource scheduling and grid operation,the model is formulated as a bi-level mixed-integer linear optimization problem.The column and constraint generation(C&CG)algorithm is employed to iteratively solve this problem,yielding optimal strategies for the coordinated operation of distribution network and microgrid during both pre-disaster and post-disaster stages.Case studies demonstrate that the proposed method can effectively ensure continuous power supply to rural loads under extreme weather conditions,significantly reduce the restoration time,and substantially enhance the resilience of rural-power grids.关键词
